I have no prior experience building a UDS. I have browsed through UDS build threads, but never really had an interest to build one until I typed in BBQ on Craigslist and found this post: http://denver.craigslist.org/bfs/1751718607.html 55 gallon steel drums for 25 bucks, but...they were filled with antifreeze. The guy even posts a link to a UDS build site. He says they would be good for a BBQ once they are "rinsed out", but Im not about to cook food in one with only a quick rinsing. Im getting the feeling he doesn't know much about BBQs and toxic chemicals. Any advice would be helpful. Seems like a good price if its salvagable. I have a powerwasher and could get it out to a friends land to burn it out if it needs it. So, two questions: 1. Is it smokable? 2. How much money will I have to put in to make a decent UDS. Thanks all!
